## Summary

The evolution of artificial intelligence has moved beyond simple response-generation chatbots toward agentic AI systems designed to autonomously execute complex workflows. NVIDIA supports this shift with its open-source model strategy, prominently featuring the Nemotron family. To build highly functional agents, developers need more than a standalone large language model; they require a comprehensive harness that orchestrates tool calling, varying CPU/GPU execution environments, memory management, and governance. Recognizing this, NVIDIA open-sources not just model weights, but also the critical pre-training datasets, alignment data, Megatron training libraries, and NemoGym evaluation frameworks. This unified stack enables developers to fully reproduce, locally test, and securely fine-tune applications for production. Engineering teams can leverage unique resources like the Nemotron Personas dataset to simulate specific regional demographics, ensuring highly localized and compliant behavior for sovereign AI initiatives. At the flagship tier, the Nemotron-3 Ultra model delivers state-of-the-art agentic performance while solving fundamental scalability challenges. Despite containing 550 billion parameters, its Mixture of Experts architecture activates only 55 billion parameters per token. Enhanced by breakthroughs like multi-teacher on-policy distillation, one-million token context windows for test-time scaling, and the NVFP4 numerical format optimized for Blackwell chips, it achieves roughly five times the token throughput of comparable trillion-parameter models. Whether configuring highly specialized sub-agents for code execution or deploying smaller vision language models to edge devices like the Jetson Nano, developers gain a highly efficient, end-to-end toolkit for building long-horizon planning applications.
